> The process of producing or using hydrogen does not pollute.

There’s no way this can be correct.

You can’t use hydrogen to produce the electricity used in hydrogen electrolysis, because that’s not permitted in this universe.[1]

Therefore the electricity has to come from some other source, which all generate life-cycle carbon emissions.[2]

In theory you could produce the H2 off planet.

Also, that tidal power looks pretty good...
